Na ostatnom stretnut\u00ed sa n\u00e1s zi\u0161lo dokopy 6. Traja fyzicky v dielni a \u010fal\u0161\u00ed traja virtu\u00e1lne.<\/p>\n\n\n\n\n\n\n\n
V pl\u00e1novanom \u010dase za\u010diatku stretnutia som e\u0161te odkladal vys\u00e1va\u010d, ale u\u017e o p\u00e4\u0165 min\u00fat som bol on-line a diel\u0148a bola vyluxovan\u00e1 dokonale. Chv\u00ed\u013eu som \u010dakal k\u00fdm sa niekto pripoj\u00ed. Ako prv\u00fd to stihol Mikezt. O nie\u010do nesk\u00f4r pri\u0161iel fyzicky Nairam na svojom e-bike. \u010ealej n\u00e1m v on-line pribudol RomBor, nesk\u00f4r Ellvis a fyzicky pri\u0161iel poobede aj Loki.<\/p>\n\n\n\n
Nairam si pripravil prv\u00fd elabor\u00e1t u\u017e pred a po\u010das svojho pr\u00edchodu. Na e-bike m\u00e1 2 bat\u00e9rie, z ktor\u00fdch jedna je o kus slab\u0161\u00eda po \u00f4smych rokoch pou\u017e\u00edvania. Dojazd jednej bat\u00e9rie je max. 60 km po rovine, pri\u010dom horsk\u00fd prechod Pezinsk\u00e1 baba sa za tak\u00fato prev\u00e1dzku rozhodne ned\u00e1 pova\u017eova\u0165. Spolu mal teda prejs\u0165 76 km \u010do by sa mu na jednej bat\u00e9rii iste nepodarilo, tak\u017ee musel zv\u00fd\u0161i\u0165 z\u00e1\u0165a\u017e e-bike o jednu n\u00e1hradn\u00fa bat\u00e9riu, aby sa nakoniec dostal aj domov. Jedna cesta mu vych\u00e1dzala \u010dasovo pribli\u017ene na 1h50m.<\/p>\n\n\n\n
Mikropo\u010d\u00edta\u010dov\u00e9 t\u00e9my boli r\u00f4zne, ale ako pri\u0161la re\u010d na Z88 u\u017e sme sa jej nepustili. Nairam sa sp\u00fdtal \u010di m\u00e1m aj tento kus hardv\u00e9ru, tak som sa priznal, \u017ee hej a nesk\u00f4r sa pridal aj Ellvis, \u017ee je zberate\u013e a moment\u00e1lne ich m\u00e1 3, z toho 2 nefukn\u010dn\u00e9. Ako som vz\u00e1p\u00e4t\u00ed zistil, ani moja Z88 sa nejavila funk\u010dn\u00e1. Zbehol som teda pre nov\u00e9 baterky, ke\u010f\u017ee bat\u00e9riov\u00e1 sekcia z\u00edvala pr\u00e1zdnotou – na\u0161\u0165astie aspo\u0148 ni\u010d nevytieklo. Pridanie bat\u00e9ri\u00ed v\u0161ak nepomohlo, tak\u017ee za\u010dalo p\u00e1tranie ako Z88 nap\u00e1ja\u0165 zvonka. Mikezt bol n\u00e1pomocn\u00fd, ke\u010f n\u00e1m prezradil, \u017ee nap\u00e1janie je 6.5V (slovom \u0161es\u0165 a pol volta) s kladn\u00fdm p\u00f3lom v strede. T\u00fdmto pozdravujeme Pola, \u017ee aj ke\u010f sa fyzicky ani virtu\u00e1lne nez\u00fa\u010dastnil, stretnutiu sa nevyhol \ud83d\ude09<\/p>\n\n\n\n
Po pripojen\u00ed na lab zdroj a nastaven\u00ed poistky na 200mA sa ni\u010d neudialo, po\u010d\u00edta\u010d sa nechcel zapn\u00fa\u0165 a po p\u00e1r sekund\u00e1ch zv\u00fd\u0161en\u00e9ho odberu okolo 40-50mA klesla spotreba na 10mA a menej – ni\u017e\u0161ie hodnoty s\u00fa na dvoch desatinn\u00fdch miestach mer\u00e1ku na zdroji nevidite\u013en\u00e9. Nadi\u0161iel \u010das na rozobratie a meranie. V Z88 je asi viac tranzistorov ako v zosilova\u010d\u00ed Sinclair System 3000, ale jeden je v jeho po\u010d\u00edta\u010doch v\u017edy k\u013e\u00fa\u010dov\u00fd – TR5. Paradoxne v sch\u00e9me st\u00e1le nesie toto ozna\u010denie, aj ke\u010f v\u0161etky ostatn\u00e9 maj\u00fa ozna\u010denie iba T a \u010d\u00edslo. Na doske ho ale n\u00e1jdete pod T5.<\/p>\n\n\n\n
Merania boli \u0161ialen\u00e9, v\u00fdsledky \u00faplne m\u00e4t\u00face, ale nakoniec som zistil, \u017ee nie je zem ako zem. Z\u00e1porn\u00fd p\u00f3l z bat\u00e9ri\u00ed \u010di nap\u00e1jacieho jacku, nie je priveden\u00fd priamo na sign\u00e1l GND na \u010dipoch po\u010d\u00edta\u010da. Preto som na nich nameral nap\u00e1janie 12V, logick\u00e9 sign\u00e1ly v podobnej hladine, ke\u010f\u017ee som mal zem sondy pripojen\u00fa na nespr\u00e1vne miesto.<\/p>\n\n\n\n
Po spr\u00e1vnom pripojen\u00ed merania za\u010dali d\u00e1va\u0165 zmysluplnej\u0161ie v\u00fdsledky, napriek tomu sa po\u010d\u00edta\u010d nerozbehol. Vyzeralo to na ch\u00fdbaj\u00face hodiny. Podozrenie padlo na kry\u0161t\u00e1l, ale ani po v\u00fdmene sa v\u00fdsledok nezmenil. Samozrejme pomedzi to prebehlo nieko\u013ekokr\u00e1t stl\u00e1\u010danie resetu a snaha o \u201cznovuzobudenie\u201d. <\/p>\n\n\n\n
Vyrie\u0161ilo sa to a\u017e po Nairamovom odchode, tak\u017ee on nakoniec ma\u0161inu funk\u010dn\u00fa vidie\u0165 nestihol. Po\u010das merania vodivosti tla\u010d\u00edtka reset pri otvorenom kryte na pr\u00eddavn\u00e9 karty. A\u017e po stretnut\u00ed som sa do\u010d\u00edtal v n\u00e1vode, \u017ee to je ten spr\u00e1vny postup – otvori\u0165 kryt na karty a dvakr\u00e1t stla\u010di\u0165 resetovacie tla\u010d\u00edtko. A tak n\u00e1m Z88 znova o\u017eila. A nebola jedin\u00e1. Podobn\u00fd \u00faspech sa podaril aj v Berl\u00edne, kde po v\u00fdmene zl\u00e9ho displeja Ellvis a Mikezt spolo\u010dne o\u017eivili \u010fal\u0161iu. Tak\u017ee Ellvis sa kone\u010dne m\u00f4\u017ee tv\u00e1ri\u0165 ako zberate\u013e funk\u010dn\u00fdch Z88, ke\u010f ich u\u017e m\u00e1 dve \ud83d\ude42<\/p>\n\n\n\n
Poobede nasledovalo \u010distenie potenciometrov paddles na C=. P\u00f4vodn\u00fd pl\u00e1n bol vymeni\u0165 ich za nov\u00e9, ale ich kr\u00e1tke a hladk\u00e9 hriade\u013eky n\u00e1m v tom zabr\u00e1nili. Bolo by treba e\u0161te na 3D tla\u010diarni vytla\u010di\u0165 vymedzovac\u00ed kr\u00fa\u017eok, preto\u017ee \u010das\u0165 v oblasti z\u00e1vitu bola na t\u00fdch nov\u00fdch ten\u0161ia. Rozhodli sme sa repasova\u0165 tie p\u00f4vodn\u00e9. Po \u0161etrnom rozobran\u00ed nasledovalo obr\u00fasenie kontaktn\u00fdch pl\u00f4ch jemn\u00fdm br\u00fasnym papierom a n\u00e1sledn\u00e9 premazanie kontaktov\u00fdm sprejom. Po zlo\u017een\u00ed a vysk\u00fa\u0161an\u00ed sa paddles javili sfunk\u010dnen\u00e9 aj ke\u010f pri konci dr\u00e1hy p\u00f4sobili dojmom drobn\u00fdch z\u00e1kmitov pri testovan\u00ed na Arkanoide. Ot\u00e1zka je, \u010di by nepomohol recap kompu, aby sa tento dojem odstr\u00e1nil.<\/p>\n\n\n\n
S RomBorom sme prebrali novinky z oblasti nov\u00e9ho Mega ROM modulu pre PMD85\u00a0 a v\u00fdvoja jeho softu okolo neho. Tie\u017e spomenul, \u017ee sa na\u0161li \u010fal\u0161ie obsahy ROM modulov do PP01. A venovali sme sa aj all-RAM re\u017eimu pre Ma\u0165a.<\/p>\n\n\n\n
Nairam chytal sign\u00e1ly z \u00e9teru pomocou ve\u013emi zauj\u00edmav\u00fdch a citliv\u00fdch k\u00faskov – konkr\u00e9tne ma zaujal Hackrf One Great Scott Gadgets, ke\u010f\u017ee som sa pred t\u00fd\u017ed\u0148om vr\u00e1til z v\u00fdletu zo \u0160k\u00f3tska, ale na tak\u00fd som veru v miestnych obchodoch nenarazil.<\/p>\n\n\n\n
Pomedzi ostatn\u00e9 aktivity som stihol predvies\u0165 zop\u00e1r zauj\u00edmav\u00fdch k\u00faskov v dielni:<\/p>\n\n\n\n
Pre \u00faplnos\u0165 dod\u00e1vam zoznam liniek, ktor\u00e9 sme si k prebrat\u00fdm t\u00e9mam vymenili v \u010dete na Jitsi:<\/p>\n\n\n\n
Obed sme vyrie\u0161ili nejak\u00fdmi grilovancami ako sa na za\u010d\u00ednaj\u00facu letn\u00fa sez\u00f3nu patr\u00ed.<\/p>\n\n\n\n
